Abstract

This paper formalizes transactional properties for publish/
subscribe client mobility and develops protocols to
realize them. Evaluations show that compared to traditional
protocols, those developed in this paper, in addition to
supporting transactional properties, are more stable with
respect to message and processing overheads. Changes in
factors such as the number of moving clients have little
impact, making the protocols more scalable and simpler to
administer due to predictable resource requirements.
